mit the circulator to be arranged between the vertical rows of tubesotthe boiler and provide walls between which the water may circulate and thereby promote and tacilitate the heating oi the water in the boiler.

litis a :turther object to provide a constructiol'i, the elen'ients 01% which may be connected together either prior or subsequent to their introductioninto the boiler and their arrangement between the tubesot the boiler.

It is another object to form the elements oi? the circulator so that when associated with each other an open ended tube is produced, one of which may be arrangei'l adjacent another within the boiler between the tubes throughout the length of the boiler. l

The invention will be explained andmore readily understood when read in conjunction with the accompanying drawings which show various structures whereby the invention may be accomplished it being therefore obvious that changes and modifications may be re sorted to without departing from the spirit of the invention as expressed in the fl.} ')1)011(l(5(,l claims :lorming a part hereof.

ll 11 the drawings:

Fig. 1 is a central vertical section of a tulmlar boiler showing my improved Water circulators associated therewith.

Fig. 2 is a horizontal sectional view of a portion of a boiler showing the circulators in side elevation;

Fig. 3 is a detail perspective view of one form of circulator conten iplated by the invent-ion and Fig. 4: is a perspective View of another form of circulator which may be employed.

The embodiment of the invention illustrau ed in Fig. 3 contemplates the provision of an open ended substantially rectangular element which. is designed to be inserted through the manhole 11 of the boiler 12 and be arranged between vertically arranged rows of tubes 13. Each of these elements 10 is of a dimension which permits of its being passed through the manhole 11, and to be located beposition with relation to the tubes.

tween said tubes as above explained and is of a length sutiicicnt to cicteinl :lfrom the upper to the lower tubes 13 between which said element is located to thus provide a passage which is transverse to the tubes "through which the water may circulate. flit is of course understood that a number oi these elements 10 are employed one being arranged adjacent another between said tubes. To accomplish this feature each elenu-ait as it is passed through the manhole and located between the tubes is subsequently moved to ward an end of the boiler to thereby provide a number of said elements 10 preferably in contacting relation with each other througln out the length of the boiler. Each of these elements 10 is provided with a means such as 14 whereby to engage the uppermost tubes and support said elements between the tubes and is i urthcr provided with a member 15 which after the elements 10 are located between the tubes is attached to each oi? said elements and caused to engage the underside of the uppermost tubeto cooperate with} the means 14 to hold each element 10 in its proper From the iforegoing description it is manifest that a means is provided whereby an ordinary boiler may be provided with a means for cansing circulation of the water without necessitating any change being made in the boiler and furthermore that these elements may be readily removed from the interior of the boiler to cleanse or repair them should this at any tin'le be found necessary or desirable.

The structure ilh'istrated in llig. It may also be employed. This structure contenn plates an arrangement which employs separable elements which whenassociated with each other form a device resembling that described in connection with Fig. 3 both as to form and operation, however provides a construction which may be assembled after with a plurality of lugs 21-21 which pro vide one part oi a holding means for securing the end members 18 and 19 with respect to the side wall members 16 and 1? the latter of which are provided with apertures 22 for ,the reception of thelugs 21 of the side wall members to thereby detachably connect the various walls together to produce a structure similar to that previously referred to.' The side walls 16 and 17 are also provided with the-holding elements 28 23 and'24c whereby "the device may be supportcdbetween the tubes 01? the boiler.

I From the foregoing description of the structure shown in Fig. 4: it is manifest that the elements of which this device consists may while in separated relation be introduced into the'boiler and be connected together after their insertion therein to term a means torfacilitating circulation of the water between the tubes 0? the b iler, whiclrnnder some circumstances is of advantage, as it is manifest that conditions will arise which would prohibit the introduction of a device formed in the manner illustrated in Fig. 3. In operation the water surrou'nding the tubes 13 becomesheated and rises to the top of the water in theboiler and, by virtue of the relatively cool water iocated mthe passages 10 which isat thistime descending in said passages, draws the \i ateiivliicli has liberated steam or become cooled through said pas- 0f theboiler, which-thus facilitates heating oi the waterand accompllsues a reduction in the cost of ope at-ion of. the boiler.

From the foregomg description of the invention' it is evident that a sunple construction is provided whereby a boiler may be provided with a means for directing the circulat'i'on. ot-thewater between the tubes andwhich may be applied to the boiler without necessitating any changebeing made thereto and which may be applied by passing the elements forming the device through an'opening'such as the manholeof the boiler.

I Having thus described the invention what I claim and desire to cover by Letters Patent is l 1. The combination with a fire tube boiler having a pair of opposed banks of tubes arranged to form a lane between them, a circulating system including a series of hori jzontally aligned vertically arranged conduits 4 providing substantially contacting units forming a part of said system, each unit being composed of dctachably united side and lint end walls, and means for supporting said conduits between said tubes of the boiler.

2. The combination with a lire tube boiler having a pair of opposed banks oi? tubes arranged to form a lane between them, a circulating system arranged in said lane, av series of horizol'ltally aligned vertically arranged conduit-s composed oi detachably united side and end walls, the end walls of each conduit being of a width throughout their length, which substantially corresponds to the width of the lane formed between said tubes, the end and side valls having means which co-opcrale with each other to allow said detachable connection of said end and side walls, the end walls of the intern'iediate conduits being arranged in substantial contacting relation with the end walls of the respective adjacent conduits.

The combination with a fire tube boiler having-a pair of opposed banlzs of tubes arranged to form a vertical, horizontally extending lane between them, a plurality of conduits located in said lane and removable therefrom by beingpassed endwise upwardly between the upper tubes forming said lane, said conduits being disposed in horizontal alignment with each other with the end walls at the"intermediate conduits contacting the end walls of the respectively adjacent conduits to thereby provide a substantially continuous vertically arranged and horizontally extending passage in said lane which forms part of a circulating system.

In witness whereof, I hereunto subscribe my name this 23rd day of July, A. D. 1926.
